I don't want to be the guy that says this show isn't super awesome but, yes I do.
Don't get me wrong I watched it start to finish for the first season and enjoyed a significant part of it. Interesting world building, interesting portrayal of death, a fantastic job of balancing the characters romantic perception's of being a soldier mixed with the reality of their situation, incredibly creepy monsters.
But to many of the characters are just tropes without depth that have been replayed over and over and over again. The less then competent idealist protagonist who get's by on sheer willpower and his grounded rival who get's by on wits alone, not one but two tragic super soldiers changed by death. The useless in a fight by super intelligent friend, the attractive ditz. Just about every character is cookie cut out, which sucks because people die left and right, lot's of them your supposed to care about but you don't slash can't because they were never really that interesting.
Also every single person in that show with the exception of the commander of the expedition force(really hoping he turns out to be a sociopath) seems to be extremely emotional. Eren loses it to something every episode, dude insults the expedition force, well Eren's gotta fight over that, some one wants to be safe behind the walls? Eren's gonna pitch a fit. Bagel for breakfast? may as well not get out of bed today. Watch mom get crushed and bitten in half? well.... actually.... ok that merits a freak out.
Like I said, I enjoyed watching it, I'll get the second season when it comes out. I'd even recommend it as a watch, but people seem to fall head over heals for this show and forget how many flaws it has.
Also pacing, it's like they said "Alright, did we make it to the climax? yes alright cut it there will do the resolution at the start of the next episode."
